EC103D2AP

Overview

The Littelfuse EC103D2AP is a silicon-controlled rectifier (SCR) designed for sensing applications. It features a maximum repetitive off-state voltage of 400V and an on-state RMS current rating of 800mA. The device utilizes a low gate trigger current of 50uA, facilitating sensitive control circuits. It operates within a temperature range of -40°C to +110°C and is housed in a TO-92 package.

Feature Summary

Low gate sensitivity with 50uA trigger current
Compact through-hole TO-92 packaging
High repetitive off-state voltage capability

Applications

Lighting control systems
Motor speed regulation
General purpose switching circuits

Procurement Notes

Verify the specific suffix 'AP' against the manufacturer's official datasheet to confirm pinout configuration and thermal characteristics. Ensure the procurement channel provides authentic Littelfuse components with traceable documentation to guarantee performance reliability in sensitive SCR applications.

Selection Notes

Select this component when a compact thyristor with high voltage blocking capability and low gate drive requirements is needed. The 800mA current rating suits light load applications, while the TO-92 form factor allows for easy integration into space-constrained printed circuit board designs requiring through-hole mounting.

Part Context

This part belongs to the EC103 series of SCRs from Littelfuse. These devices are engineered for general-purpose switching and phase control applications. The series offers various gate sensitivities to accommodate different control logic levels while maintaining robust electrical performance across industrial temperature ranges.

Replacement Considerations

The EC103D1AP is a documented alternative within the same family, offering identical voltage and current ratings but with a different gate trigger current specification. Verify compatibility regarding gate drive requirements before substitution.
